Bought this as I needed a small mixer for live performances involving violin player, iPad, and laptop. The pre-amps are very very good, I am surprised to say, they made a normally bad instrument output sound much much better. Worht it for that feature alone. The whole mixer is well built and well-designed, tosave space on two extra knobs for panning, they simply ahve a little button that converts 2 x mono channels to stereo.
